What is next after Paradigm Studio S-40


I had a simple and nice system 3 months ago: Pioneer F-705 CD player, Rotel pre/power - 960BX and Paradigm Studio S-40 speakers.
I decided to upgrage the system and now I have: Bryston BP-25 preamp, Bryston 3B-ST power amp and Arcam CD-72 CD player. It seems that my speakers are the weakest link in this system.
What speakers would you suggest to try? I have already tried Totem Mani-2 (too dry and flat unless you put very expensive wires), PMC LB2 and FB1 - I did not like bass and soundstage.
Paradigms sound great and this is the sort of sound I like.
So, what is similar to Paradigm sound (open with good mid-bass) but more detailed and acurate? Or may be I need to upgrade cables? (I have audioquest Slate speakers cables and Audioquest Coral interconnects).
Thanks, I appeciate your time.

The Paradigms' failings to me are always about an inherently second-class midrange. Top octaves can be tamed with positioning and room treatment, and bottom octave is a function of that plus the size you buy. No quarrel with Paradigm's bang-for-the-buck bottom end, as MDF is essentially free in Canada, and they make good woofers.
I started my search a few years ago with the 20 and 40, and quickly became enamored of better midrange drivers, especially when care in pair-matching is well-performed.
For under $2k the two favorites of mine are the Spendor S3/1p for a warmer spectral tilt (casual listening, lively room, FM and HT...and women!), or the Revel M20 for a more linear, high-rez spectral tilrt that demands better components. At paradigm's price-point they just cannot pair-match and still give you that much bass, and again , their forte is NOT a super-pure midband like Spendor, Harbeth, Revel, and a few others I'm sure other guys will mention. Depends what you want. Rock the house? The Studio 100. Sublime tonal honesty? Look elsewhere....
I would put the Quad 12L in the same breath as SPendor and Revel monitors...not as dark or forgiving as Spendors...more in common with the uncolored, high definition sound of Revel...but a very open, coherent, and dynamic midrange...and less than half the price...Quad 11Ls are very nice for smaller rooms...I would also agree with Subaruguru...if you are going to upgrade...might as well do it right
I haven't heard the 12L, but if it's a better than the nice 11L, and has a great midband than I certainly agree with Phasecorrect, as the 11L is almost as good as the Spendor S3/5 in many ways.
